Consider a string with length 36 cm. The two ends are attached to the ceiling, separated by distance 30.0 cm. A 1 kg mass is attached to the string at distance 15 cm from the left end. Then the mass hangs suspended in Earth's gravity.
(a) Determine the tension in the left segment of the string.
(b) Determine the tension in the right segment of the string.
